Abstract: 136,745. Erlinger, G. April 8, 1919. Working-flow supply; combined-flow type. - The invention relates to combustion-product generators and is shown applied to the driving of a turbine. The turbine 20, Fig. 1, is mounted upon a base containing a compressed-air reservoir 21, to which air is supplied from a series of pumps driven off the shaft. 26 geared to the turbine shaft 27. The generating-apparatus is in duplicate. each part comprising a valve casing 34, Figs. 3 and 6, containing a piston valve 35. Adjacent to each valve is a combustion chamber 36. The valve casing 35 is provided with ports 71 leading to the atmosphere, ports 39, 40 leading to the combustion chamber direct, port 72 leading to the combustion chamber by way of a pipe 73, port 75 leading to the compressed-air reservoir 21, and ports 39, 68, 70 leading to the inlet conduit 31 of the turbine. The piston valve 35 is provided with a piston-rod 49 passing through the cylinder head 47 and carrying a piston 50 working in a cylinder 51, the outer end of which is air-tight and the inner end open to the atmosphere by way of a port 53. The other end of the valve 35 is fitted with a rod 55 carrying a piston 59 working in a cylinder 58. The piston 59 carries a rod 60 fitted with a projection 62. The pistons 35, 50, 59 form a solid assembly and reciprocate together. The function of the piston 59 is to pump explosive mixture from the carburettor 82 to the explosion chamber 36 by way of a pipe 100. The function of the piston 50 is to return the valve system to the right-hand position at the conclusion of each stroke, by reason of that vacuum created in the outer end of the cylinder 51. The cycle of operations is as follows. The combustion chamber 36 being charged with explosive mixture during the previous stroke, compressed air from the reservoir 21 passes into the combustion chamber by way of the ports 75, 40. The pressure is communicated by way of pipe 73 to the space between the end of the valve 35 and the cylinder head 47, whereupon the valve assembly is moved from right to left. The air-supply ports 40 are then closed, and the projection 62 on the rod 60 engages a make-and-break device 114, whereupon the charge in the chamber 36 is ignited. The valve continues to move to the left, and the ports 39 are uncovered; the combustion products then 'flow to the turbine. The continued movement. of the valve 35 to the left uncovers the ports 75, 40, and a scavenging-charge of air is admitted to the chamber 36 from the reservoir 21 and thence to the turbine. The vacuum created behind the piston 50 then causes the valve assembly to be moved from left to right. The piston 59 forces a fresh charge of gas into the chamber 36 by way of a pipe 100, and the above cycle of operations is repeated. The turbine to which the invention is applied comprises a casing with tangential inlets 31, 32, Figs. 1 and 11, leading to a ring of nozzles adjacent to an impact-wheel with blades 140. The gas leaves the impact-wheel laterally, passing through stationary guide-blades 146 to axial-flow blades 144, 145 mounted upon the same rotor as the impact blades 140. The motive fluid then passes through fixed deflexion blades 148, 149 to outlets 152, 149 to outlets 152, 153.
